Tannery wastewater contains large amount of chemical compounds including toxic substances. So an attempt was made to characterize physiochemical parameters of tannery wastewater and investigate the efficacy, and applicability of the biological treatment utilizing aquatic plants macrophytes and algae. Total suspended solids TSS and total Dissolved solid in the original wastewater were found 1250 mg/l and 21300 mg/l respectively. The pH and temperature were 8.3 and 29°C. Dissolved Oxygen (DO), Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) were 2.72 mg/l, 4464 mg/l and 12840 mg/l respectively. Electrical conductivity (EC) was 42500 ?S/cm anions PO43- and Cl- were 17.1 mg/l and 13.8 mg/l respectively. Heavy metals were also analysed. Fe, Na, Zn, Cr, Pb and Ca were found 14.675 mg/l, 12006 mg/l, 1.5241 mg/l, 10.348 mg/l, 0.1818 mg/l and 0.4112 mg/l respectively. Biological treatment with aquatic plants, algae and their combination treatments were found to be effective for the reduction of some physiochemical parameters. Treatment conducted with Eichhornia crassipes was found most effective in reducing COD, EC, TDS and TSS. Mixed treatment resulted reduction of pH from 8.3 to 6.21. Both macrophytes and algae exhibited good heavy metal uptake tendency, but Eichhornia crassips was identified as most effective for the removal of heavy metals in the wastewater because of its extensive root system which provides to help the uptake of pollutants from the wastewater.

Analyzing antibiotic susceptibility pattern of uropathogens help to overcome the therapeutic difficulties created by the rising antimicrobial resistant bacteria and guides in choosing appropriate antibiotics. Hence, we aimed at evaluating the pathogens causing UTI and study their antibiogram. Midstream urine samples were collected, cultured and appropriate biochemical tests were performed for proper identification of urinary pathogens in BSMMU from January 2013 to December 2013. The most common isolated Gram negative uropathogens were Escherichia coli (63.93%) followed by Klebsiella pneumoniae (17.09%), other bacterial species, named Pseudomonas spp. Enterobacter Acinetobacter spp. Citrobacter spp Proteus spp. Morganella. Among Gram positive organism S. aureus S. saprophyticus S. agalectiae and Enterococci were found. Urinary tract infections were more prevalent in women than men (61.68% vs. 38.32%). High level of sensitivity was found to imipenem, amikacin, nitrofurantoin, ceftriaxone, gentamicin, cefuroxime in most of the isolates. Almost all the test organisms exhibited multiple antibiotic resistances. The high multiple antibiotics resistance identified makes it necessary for antibiotic susceptibility testing to be conducted prior to antibiotic(s) prescription.Bangladesh J Med Microbiol 2016; 10 (01): 22-26

Introduction:Early blight is a common disease of tomato, which is caused by Alternaria solani. Objectives:This work was accompanied to find an alternative to chemical fungicides and to screen tomato varieties against Alternaria solani. Methods:The infected leaves were collected from five tomato fields of Shere-e-Bangla Agricultural University, Dhaka and were cultured for the identification of the infectious fungus and The phytobiocidal role of six plants against Alternaria solani was evaluated in vitro model. Results & Discussion:Alternaria solani was identified as the infectious fungus. The growth of the test fungi Trichoderma spp. viz., Trichoderma viride, T. harzianum collected form NAMDEC and Trichoderma sp collected from field of BCSIR was monitored as optimum P H . All the selected Trichoderma spp. were antagonistic to A. solani. Antagonistic capacity of the Trichoderma spp. was tested by dual culture, volatile as well as non-volatile method. It was observed, T. viride was most effective in the reduction process of A. solani and T. harzianum. T. viride also showed highest inhibition in volatile and non-volatile trials. Six plant extracts viz., Adhatoda vasica (Nees), Azadirachta indica (A Juss). Ocimujm sanctum (L), Allium sativum (L), Datura metal (Linn) and Zingiber officinale (Rose) were selected to evaluate their in vitro efficacy of 5%, 10% and 20% concentration against the A. solani. Allium sativum was the most effective one against A. solani, followed by Azadirachta indica. The efficacy of five fungicides viz., Bavistin 50WP, Mancozeb 80WP, Indofil M-45, Sulcox 50WP and Tall 25EC were evaluated for their fungitoxicity against the A. solani at 100, 200,100, 600 and 800 ppm. Tall 25EC was the most effective fungicide against Alternaria solani followed by Mancozeb 80WP. After screening the five tomato varieties against A. solani, it was revealed that BARI Tomato-9 had the highest Percentage of Disease Index (PDI) and the leaf of BARI Tomato-7 had the lowest Percentage of Disease Index (PDI). Conclusion:The extract of Allium sativum was effective to control Alternaria solani at prescribed concentration. The highest PDI was found in BARI tomato-9 against Alternaria solani.

Immature reticulocyte fraction a new routine parameter in the hematology analyzer can give the idea of the earliest morphologic change of bone marrow recovery before other test become positive after chemotherapy. A prospective observational study was carried out in the Department of Clinical Pathology in collaboration with Paediatric Haematology and Oncology, Bangabandhu Sheikh Mujib Medical University during a period of one year starting from October 2009 to September 2010 to evaluate the bone marrow recovery in children with acute lymphoblastic leukaemia by automated reticulocyte analysis. Total fifty patients were enrolled in this study on remission induction phase. All patients were between 8 months to 15 years age range with a mean age of 5.5 ± 3.2. At the end of the study out of 50 cases, 52% patients showed early immature reticulocyte fraction recovery and concluded that the immature reticulocyte fraction parameter showed earlier haematopoietic recovery than the current practice of absolute neutrophil count recovery.
